A switch module includes a switch integrated circuit (IC), a photonic integrated circuit (PIC), and a planar lightwave circuit (PLC). The PIC may include a plurality of light sources, an optical splitter, and a plurality of modulators. A dual MEMS may be used to align lens arrays, which may be used to couple light from the PIC to the PLC.

Optical module for terabit switch

Light from discrete red, blue, and green lasers are combined into a single output using a planar lightwave circuit (PLC). In some embodiments some light from an output of the PLC is reflected back to the lasers, and in some embodiments the reflected light is primarily of one of the red, green, or blue wavelengths. In some embodiments multiple lasers of slightly differing wavelengths are provided as light sources for some or all of the red, blue, and green light.

RGB combiner using MEMs alignment and PLC

An optical transceiver may include pairs of lasers, each laser of a particular pair generating light at the same wavelength and each pair of lasers generating light at different wavelengths. The light from the lasers may be demultiplexed onto a pair of outputs, with each output receiving light from different lasers of each pair of lasers.

QSFP double density module

A transmitter assembly incorporating multiple laser diodes that are wavelength multiplexed together using a planar lightwave circuit, and where the multiplexer's transmission spectrum depends on temperature at the same rate as the laser diodes. This allows a design for lower loss in the multiplexer and therefore is more power efficient.
